This paper presents a report of a second intensive ornithological survey over a square mile of cultivated prairie. The first survey was made on July 25 and 26, 1916, by Dr. Arthur R. Abel, who was at that time a student in Morningside College, Sioux City, Iowa. The report of this survey was published in the Proceedings of the Iowa Academy of Science, Vol. XXVII, 1920, pages 385 to 393 inclusive. It was thought that a repeated survey over the same ground after an interval of ten years, would be both interesting and important. It was not possible for the writer of this paper to be in this territory on the same dates as those chosen by Dr. Abel; therefore, a number of discrepancies which may appear in this report may be attributed to the difference in time. The present survey was made on June 10, 1926.
